We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Insect-size flying robots are under development.
Our governments promise never use them against us.
Remember their promise not to use our social security numbers as national IDs to track us?
American privacy is moribund.
American freedom is in the E.R.
These are not the threat - the threat is from autonomous nanobots that you inhale or ingest which will track your every movement, thought and action. :>)
Well then, I guess we need hunter killer quadrocopters to hunt down the invaders. Every home a castle, every day a battle. Hey, I bet that would drive weapons innovation to WWII levels.
Wake up We the People! Seems like everything under 500 ft agl is non-Federal airspace, therefore still owned by Us. So it's pretty simple: any drone under 500 ft specifically gathering information on a "person of interest" requires a served search warrant. So if you see a drone hovering or orbiting over your property, and you haven't been served with a warrant, or agreed to by a private operator, you will assume it's illegal, and are free to defend your property rights.
In about one year we'll see the first privately made example of somebody with a laser that ionizes a channel for a lightning bolt to travel through. That's gonna be an awesome toy. I bet they'll call it the phaser. There's the drone killer. You should also be able to create your own RC drone kamikaze. They sell 'em now at the local RC shop. Since the drone is looking down, the operators will never know why they suddenly crashed.
And don't forget: paint-ball ack-ack, from a compressed-air spud gun, use an optical tracker with autofocus to get elevation and distance,and drive the az/el servos. Just need a way for the paint ball misses to disintegrate before they come back down.
